LM-80 Data
Results from Curve Desk Lamp Lumen Maintenance Testing And
Use Of IES LM-80-08 Data
This report is provided by Finelite Inc. and applies to lumen maintenance testing for the Curve desk lamp.
The purpose of this document is to describe the procedure used to determine the published L70 lifetime rating for
the Curve luminaire and demonstrate that current industry standard procedures have been followed in the reporting
of Curve LED life.
LED lumen maintenance lifetime estimates for the Curve desk lamp are based on two primary sets of data:
(1) Independent tests performed on a sample Curve luminaire, under standard conditions
These tests determine the Curve LED temperature performance in normal operation. Finelite utilized
services from Lighting Sciences to obtain this data. The Lighting Sciences report contains In Situ
Temperature Test Results for the Curve desk lamp based on the testing methods prescribed by the DOE
Energy Star® program for Solid State Lighting and IES LM-80-08. [Refer to Attachment A.]
(2) Lumen maintenance of the individual source LEDs under specific temperature and power conditions
This data comes from the manufacturer of the LEDs at a component level. Finelite uses Cree® LEDs in
Curve, and Cree has provided lumen maintenance data for their specific model LED used in the Curve
desk lamp. In its efforts to provide customers accurate and useful product data, Finelite has worked
extensively with independent test facilities and LED manufacturers to test and qualify its LED lighting
products. In accordance with standard industry practice, the lifetime data contained in this report
follows test procedure IESNA LM-80-08. LED Case Temperatures (Tc) are used to characterize thermal
performance and predict L70 lifetimes. LED Case Temperature can be directly measured during
independent testing, and LED manufacturer lifetime data is based on controlling and modifying this
Case Temperature over an extended period. [Refer to Attachment B.]
When combined, these data sets provide a method for Finelite to estimate the lumen maintenance of the Curve
luminaire. Data from the Curve desk lamp as presented serves as a conservative estimate of life. Measured data
and L70 lifetime estimates are summarized below.

a.
LED case temperature Tc (also referred to as the solder point temperature Ts)
This is the location on the LED where the temperature measurements are taken since it is
not physically possible to measure the LED junction temperature (Tj) directly. Tc is used to make
indirect temperature measurements of Tj. Refer to Attachment A for Lighting Sciences independent
test measurements of Tc.
b.
Cree®-measured lumen maintenance data
At 6,000 hours of operation, the Cree LEDs maintain over 99% of their initial light output (lumens).
This lumen maintenance data is based on conditions of operation in Curve luminaires.
c.
Cree engineering estimate of L70 Lifetime
The L70 Lifetime represents the number of hours where 70% or more of initial light output (lumens) is
maintained. Finelite has submitted the Curve thermal testing results to Cree for review. Their engineers
provided the L70 +100K hour lifetime estimate based on internal testing performed by Cree and informed
by their substantial experience with LED chip, package, and phosphor technologies. [Refer to Attachment B.]
